To all whom it may concern.'

Be it known that we, CHARLEs C. BARCLAY and FREDERICK IIAOHMANN, citizens of the United States, residing at St. Paul,l in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Car-AxleeBox Lids; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved car axle box lid, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention in its preferred form is illustrated in the accompanying drawings, wherein like characters indicate like parts through out the several views.

Referring to the drawings, Figure 1 is a view in side elevation, with some parts broken away, showing a car axle box equipped with a lid designed in accordance with our invention. Fig. 2 is a front eleva tion of the parts shown in Fig. l. Fig. 3 is a vertical section taken approximately onl the line :r3 003 of Fig. 2. Fig. 4 is a fragmentary view on the same line as Fig. 3, showing the lid in a raised position. Fig. 5 is an inside elevation of the lid, some parts being broken away. Fig. 6 is a horizontal section taken approxi Fig. 7 is a section on the line x7 x7 of Fig. 6 and Fig. 8 is a detail in section taken on the irregular line x8 .rs of Fig. 7, some parts being broken away.

The car axle box 1 is provided with `an annular lid seat 2, the rim of which is preferably rounded in cross section, as best shown in Figs. 3, 4 and 6. Above the lid seat 2, the box is formed with a pair of heavy bearing lugs 3 in which the ends of a short shaft 4 are rigidly secured. The intermediate portion of this shaft 4 is angular and, as shown, is reduced and formed on its upper portion with a lock flange or key like projection 5.

The lid 6 is of disk like form and is providedin its inner face near its outer edge with an annular groove 7 that is adapted to closely it the annular rim seat 2 of the box. This lid 6 is shown as provided with a pair of bearing lugs 8 that work pivotally on the hinge bolt 4 between the box lugs 3. Also these lugs 8 in their bolt seats are formed with lock notches or lock flange seats 9 which when the lid is raised as shown in Fig. 4, are adapted to engage the lock rib 5 of the bolt 4, and thereby support the said lid in its open position. A rotary hub 10 is rotatively seated in the central portion of the lid 6, the 1 same, as shown, having an exterior flange 1()a that limits its inward movement. A short heavy clamping bolt 11 is rotatively mounted in the hub 10 and at its inwardly projecting end has threaded engagement at 11a with the intermediate portion of the lock bar 12. At its outer end, the clamping bolt 11 is provided with a large head through which acombined handpiece and latch 13 works, with freedom for oscillatory-and endwise movements. This latch or lock bolt 13 is provided with a curved handpiece 13a, and the downwardly projecting end thereof is adapted to be engaged with any one of several lock notches 14 formed in the lower portion of the outer rim. of the lid 6. The bottoms of these lock notches 14 (see Fig. 3) are inclined with respect to the plane of the lid and thedepending end of the latch 13 is beveled at 13b for engagement with the said inclined bottoms. Vith this construction, when the latch is turned parallel to the plane of the lid and is then slid downward into engagement with one or the other of the notches 14, the said latch will be held against oscillatory movements on the axis of the clamping bolt 11 and will also be held against rotary movements on its own axis, thus serving to normally lock the latch in its 'operative position shown in Figs. 2 and 3.

The lock bar 12 is adapted to vibrate between stop lugs 15 and 16 on the inner surface of the lid 6, and it is put under yielding strain to maintain engagement with the said lug 15 by means of a spiral spring 17, one end of which is attached to said bar, and the other end of which, as shown, is attached to the said lug 16. The ends of the said lock bar 12 are adapted to be engaged with lock lugs or shoulders 18 formed on the interior of the box adjacent to the lid seat 2. The faces of these lugs 18, as well as the engaging endportions of the lock bar 12, are preferably rounded slightly, as shown in Fig. 8, to facilitate their engagement.

The lock bar 12 is caused to rotate with the hub 1.0, as shown, by means of a screw 19, the reduced end of which works telescopically within a seat 2O of said hub 10, so that this connection permits a lateral movement of the lock bar 12 with respect to said hub and with respect to the lid 6. A driving projection in the form of a pin 21 is secured to the outer face of the hub 10. y t

There is sufficient play between the hinge bolt 4 and the seats therefor in the lid lugs 8 to permit the lid always to be tightly seated against the annular seat 2 of the box, and also to permit the notches 9 to be readily engaged with and disengaged from the lock flange 5 of said bolt. To release the said lock notches 9 from the lock flange 5 when the lid is held in its upper position, as shown in Fig. 4, it is only necessary to press laterally upward on said lid. l/Vhen the combined latch and handpiece 13-13a is raised and turned outward, the clamping bolt 11 may be rotated thereby. From the position shown in Fig. 2, the said latch may be oscillated in the direction of the movements of the hands of a clock far enough to release the ends of the lock bar 12 from the cooperating lock lugs 18, and under further movement in the saine direction the said latch will strike the pin 21 of the rotary hub or tumbler l() and cause the same, and, hence, the lock bar 12 to oscillate with 'the said clamping screw. By this movement, the ends of the clamping bar 12 are thus relieved from pressure against the lugs 18 and are then turned out of alinenient with the said lugs, so that the lid may be swungI outward into an open position. This oscillatory movement of the latch bar 12 is, of course, accomplished against the tension of the spring 17.

1n closing the lid, the latch, the hub, the clamping bolt and the lock bar must, of course, be moved into the position just noted, so that the ends of the said lock bar will pass inward clear of the lock lugs 18; and then when the lid has been seated the lock bar by means of the combined latch and handpiece should be moved in a direction reverse from that indicated by the arrow marked on Fig. 2 so as to carry the ends of theflock bar 12 into engagement with the inner surface of the lock lugs 18, as shown in Figs. 7 and 48. The stop lug 15 limits the movement of the lock bar in the direction just stated to the said position shown in Figs. 7 and 8, but the clamping screw 11 must be moved further in the same direction so as to draw the lock bar laterally toward the lid, 'or otherwise stated, the lid laterally towards the lock bar, and thereby tightly force the lid against its annular seat 2 and the ends of the said lock bar against the said lock lugs 18. As already indicated., the tension of the spring 17 is in the proper direction to prevent the lock bar from being jarred or otherwise accidentally moved from its locked engagement with the lugs 18. Nevertheless, any such accidental movement of the lock bar from its operative position is positively prevented by the latch 13 when the latter is engaged with one or the other of the notches 14, as shown in Figs. 2 and 3. The several notches 14 are provided so that the said latch may be secured in any one of several positions as may be required to clamp the lid with the proper pressure against its seat on the box.

By reference to Figs. 3 and 6 it will be noted that the spring 17 is of such form that it also acts to press the lock bar laterally away from the lid and thus hold the head of the clamping bolt 1.1 against the outer face of the hub 10, and the flange 10a of said hub against the outer face of the lid. By reference to the same views it will also be noted that the lid inward of its rim is dished or set inward of the outer portion of the said rim, so that the projecting portions of the hub 1.0, of the clamping screw 1.1 and of the combined latch and handpiece 13 13ZL when the lid is locked are contained nearly or entirely within the limits of space occupied by the lid and, hence,

are not exposed where they are liable to get knocked ofl.

Form the foregoing description and statements made, it will be seen that the coperat# ing locking elements for securing the said lid to the box are located within the box when the lid is closed, but are provided with operating connections which extend t'o the exterior of the box, so they may be moved into and out of coperative relation from the exterior of the box. This is a very important feature and is believed to be broadly new.

What we claim is:

1. The combination with a box and a lid hinged thereto, of a lock bar intermediately pivoted to said lid on the inner side thereof and engageable with cooperating parts on the interior of the box, a clamping bolt extending through said lid and having threaded engagement with said lock bar and provided at its outer end with a handpiece by means of which it may be oscillated, substantially as described.

2. The combination with a box and a lid hinged thereto, of a lock carried by the lid at the inner side thereof and engageable with cooperating parts on the interior of the box, a lock operating connection extending through said lid to the exterior of the box, and a latch for holding said lock actuating connection against movement and the said lock in an operative position, substantially as described.

3.
